This paper summarises the regulation mechanism of traditional and emerging surface strengthening treatments – mechanical shot peening (SP) laser shock processing (LSP) treatment, respectively on fretting fatigue behaviour tenon joint materials aero-engine cold-end parts, as treatment contributes to improvement service performance. From point view actual environment turbine components, this also expounds key problems faced by in improving properties for hot-end components. The application LSP...
The stress effect generated by a high-energy short-pulse laser is utilized to achieve performance enhancement or precise shaping of metal material components in shock technology. A method marking materials using technology introduced this paper. physical principle the thickness absorbing layers on intensity laser-induced shockwave, which results forming mark with certain shape local surface plastic deformation. based overcomes deficiency traditional methods that causes serious damage and...
Statistical analysis of white-light interferometry (WLI) experiments performed on Ni-based single-crystal superalloys (SX) have revealed a different height distribution between the dendritic cores (DCs) and interdendritic regions (IRs) polished samples. The micromechanical property difference is largely ascribed to uneven alloying elements. In this context, possible reasons for are discussed by comparing with experiment results obtained previous researchers, proposal forecasting hardness...
The appearance of the residual stress hole (RSH) phenomenon makes otherwise perfect laser shock processing (LSP) method potentially defective. Residual compressive distribution appears in areas irradiated by beam while central position pursues tensile individually. This is prominently seen numerical simulation LSP experiments. However, authors find that existence RSHs ill-defined most published testing results. A hypothesis cavitation effect inhibits formation based on application water...
The effect of volume energy density and deposition on the roughness, porosity, hardness laser beam powder bed fusion (LBPBF) GTD222 Ni-based superalloy was systematically studied. results showed that roughness porosity alloy decreased with increase two densities, while increased. When exceeded a threshold value, reached maximum value almost remained constant. could be used to estimate conditions for obtaining high-density LBPBF more accurately than density. process parameters transformation...
